Did you know that several years before Jon Hamm became an award-winning TV star, he was teaching drama at John Burroughs High School in St. Louis?

And did you also know that one of The Office’s finest was one of his students?

Turns out, long before Jon was kissing Tina Fey and January Jones, all the high schoolers wanted to kiss him. “He was a heartthrob!” the mystery gal gushes of her former teacher turned Mad Men megastar. “All the girls would sign up for his class…for a good reason!”

So who is it? Here’s a hint: She has brownish-hair, has played the receptionist, and has been one-half of one our favorite will-they-won’t-they couples (which we’re also giving dish on here)…

Supercute new receptionist, Ellie Kemper!

“In addition to being really handsome, he was an excellent teacher,” Ellie tells us. “He taught me drama work, mostly improvisation, which I did a lot of in college and in New York. It’s my favorite thing to do.” It’s nice to know Jon’s not just another pretty face, but brilliant in the classroom, too.

We discovered this connection from Mr. Hamm himself, who told our Ashlan Gorse at Sundance: “One of my students is actually Ellie Kemper, who’s now on The Office. It’s really cool to see them blossom and find their own way in.”
